HOLLOW METAL DOOR-FRAME.

Specification of Letters Patent.

Patented July 2, 1912.

To all whom it may concern:

Be it known that we, ALFRED J. ELLIS and CHARLES E. NELLIS, citizens ofthe United States, residing, respectively, at Woodcliffon-Hudson,township of North Bergen, county of Hudson, State of New Jersey, andcity of New York, borough of Brooklyn, State of New York, have inventedcertain new and useful Improvements in Hollow Metal Door-Frames, ofwhich the following is a full, clear, and exact description.

This invention relates to hollow metal door frames, and has for itsobject the simplification of such structures providing a hollow metaldoor frame the parts of which may be readily assembled; our constructionalso obviatingthe necessity for extreme exactitude in laying out bolt orscrew holes,

and the like. The frame is preferably composed solely of straightmembers, means being provided for. uniting such members to form aunitary structure. 1

A further object of our invention is to provide means integrally formedwith certain of the said members whereby the latter may be firmly lockedin position in brickwork or the like.

Other objects of our invention will be hereinafter set forth and moreparticularly pointed out in the appended claims.

Referring to the drawings which form a part hereof: Figure 1 shows anelevation of our improved door frame construction, the left hand side ofthe molding thereof being broken away to show some of the details ofconstruction; a small section of the jamb and coiiperatin parts beingfurther broken away to provid e a fragmentary section substantiall onthe line II of Fig. 2. Fig. 2 is a ragmentary section of our frame,taken on the II-II of Fig. 1, the section being viewed as indicated bythearrows in Fig. 1. Fig; 3 is a perspective view of one end of one ofthe upright bucks. Fig. 4 is a fragmentary detail showing means foruniting the buck members. Fig. 5 is a perspective view of a left handupper corner of the assembled jamb, viewed from above. Fig. 6 is adetail of one of the molding clips.

Like reference characters designate like parts throughout the severalviews.

Referring to the drawings, the vertical jamb sect-ions have been broadlydesignated 1, and the corresponding horizontal jamb section 2. Thesejamb sections are provided with suitable moldin 3 and are adapted toreceive the door l, in the usual manner. .Each of the individualsections is virtually U- shaped, one of the legs of the U, as viewed incross section, bein designated 5, and the other 6; the leg 5 beingconsiderably longer than leg 6 for reasons hereinafter set forth. Theexposed face of the jamb is rovided with a molding. Upon either sid ofthe molding 8 of each of the jamb sections are flat portions]? and 8,and such flat portions in the horizontal sections are adapted toslightly overlap corresponding parts of the vertical sections, or viceversa, as indicated in Fig. 5; the horizontal overlapping section thereshown being slotted at 9 for the reception of projections or tongues 10which extend upwardly from the corresponding portion of the adjacentsection; such tongues being adapted to be bent over so that the partsmay be firmly locked together. Additional tongues 11 may correspondinglyproject from the overlapping section, such tongues being bent downwardlyand inwardly toward and into contact with the adjoining section, therebystill more firmly locking the parts together.

The buck for our assembled jamb sections is similarly formed of twovertical members and a horizontal upper member; such members beingrespectively designated 12 and 13. These members are adapted tointerlock in the manner shown in Fig. 4;, the vertical members beingslotted as at 14 for the reception of tongues 15, which extend outwardlyfrom and in alinement with the web of the buck member 13. We prefer tobend such tongues over alternately in opposite directions in the mannershown in.'

Fig. 4, whereby the respective elements are very securely unitedtogether. The flanges of all parts are preferably cut at 45 as shown at16 in Fig. 3. The vertical buck members '12 have a series of U-shapedcuts 17 therein and'the tongue 18 so formed is pressed outwardlysubstantially at right angles to the body of the member, as in Fig. 3.We prefer also to corrugate such 1 and by reason of this fact it becomespossible to insert the assembled jambstructure into positionwithin thewall inclosed buck, the flanges 6 of the jamb and flanges 21- of thebuck being narrow enough to permit of such insertion. After the amb hasbeen so positioned, it may be secured to the buck in any suitablemanner, as by screwsor bolts 22,

which engage the wider flanges of the buck and the narrower flanges 6 ofthe jamb, 20 while corresponding screws or bolts 23 on the other side ofthe door secure the flanges 5 and 21 together. On the hinge side of theI door, U-shaped hinge irons or strips 24: are

secured at spacedintervals to the inner sides of the flanges of thejamb, a bolt 22 in such cases passing through one of the legs of suchU-shaped strip, while the other end of said strips may becorrespondingly fastened by means of a bolt'25. We preferto recess ofslot the exposed face of the jamb for the reception of the fixedelements 26 of the hinges 27, and hence these members may be directlysecured to the hinge strips by means of screws or bolts 28. The webs ofthe buck members are slotted adjacent the edges thereof .at spacedintervals as indicated at 29 in- Figs. 3 and 4, and substantiallyL-shaped clips 30 are provided for engagement. with these slots,theinner or at 31 so as to neatly engage the webs. The shorter andlaterally projecting legs of these clips areslotted as shown in Fig. 1for the reception of bolts 32. A buck having been built in position;either before or, afterthe jambis. placed therein, .the clips 30 arehooked into engagement with the respective slots, and the plaster 33 isapplied therearound.- This plaster serves to temporarily hold the clipsin position so that they pro- .ject outwardly from the face thereof, andthe respective sections of molding 34 are then applied-to the face ofthe plaster and into engagement with the jamb flanges 5 and 6, theinwardly projecting flanges of the moldings 34 entering into andembeddingtheir edges in the plaster as at 35, the bolts 32being' screwedsecurely into place ,tolock the several partstogether. Bolts 32 arepreferably provided with nuts 36; and the clips 30 are slotted at 37 inthe manner indicated in Figs. 1 and 6, so that a certain amount of playis allowed in order that the respective molding sections may be neatlyfitted together. The provision of slots 37 longer legs of such clipsbeing hooked as in the clips and slots 29 substantially at right angles\to such slots in the webs of the buck'sections, allows for adjustmentof the molding sections in all lateral directions and obviates thenecessity for any great 'exacti-- tude in the positioning of bolt holesand the like.

It will thus be seen that our com frame construction may be most readilyassembled,

preferably but one portion of the same, to wit, the buck, being built,into the brickwork at the time such brick-work erected, the remainingportions being adapted to be applied thereto after the wall has beenfaced with plaster.

What we claim, is a 1. In a hollow metal door frame, a sheet metal buckhaving flanges upon opposite sides thereof projecting from the body ofthe buck out into'the door space, flanges on one side of said doorprojecting more than the flanges on the other side,'a jamb insertibleinto said buck, and means for securing said jamb in: place, said jambbeing adapted for direct engagement with the sald flanges.
